REPLY FIELDS response_type The type of this reply, in this case XCB_QUERY_FONT. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each oth- er. sequence The sequence number of the last request processed by the X11 server. length The length of the reply, in words (a word is 4 bytes). min_bounds minimum bounds over all existing char max_bounds maximum bounds over all existing char min_char_or_byte2 first character max_char_or_byte2 last character default_char char to print for undefined character properties_len how many properties there are draw_direction One of the following values: XCB_FONT_DRAW_LEFT_TO_RIGHT TODO: NOT YET DOCUMENTED. XCB_FONT_DRAW_RIGHT_TO_LEFT TODO: NOT YET DOCUMENTED. min_byte1 TODO: NOT YET DOCUMENTED. max_byte1 TODO: NOT YET DOCUMENTED. all_chars_exist flag if all characters have nonzero size font_ascent baseline to top edge of raster font_descent baseline to bottom edge of raster char_infos_len TODO: NOT YET DOCUMENTED. DESCRIPTION Queries information associated with the font. RETURN VALUE Returns an xcb_query_font_cookie_t. Errors have to be handled when calling the reply func- tion xcb_query_font_reply. If you want to handle errors in the event loop instead, use xcb_query_font_unchecked. See xcb-requests(3) for details. ERRORS This request does never generate any errors.
